Braces tighten feel of the car, reduce NVH, but don't make it faster so don't do those for speed. Ideally do overlay of data with the guy beating you, best ...

I received the Roadstersport II, and I wanted to compliment you guys on an awesome product. The Miata should have these on from the factory. They make a great sound, that is not obnoxious at all. The exhaust also installed seamlessly!!! I will buy all of my Miata stuff from you in the future.
Thanks,

Brian,
Thank you!!!
We last spoke in November about some upgrades for my 2011 MX5 soft top. It
has finally warmed up in NE Ohio and two relaxed weekends of wrenching on my
car were well worth the effort.
Installation of the RoadsterSport ceramic coated street header was straight
forward and took under 8 hours, including a 40 minute test drive and cleanup
of the garage! Combined with the RoadsterSport Q exhaust, the sound is
fantastic and the increased torque, horsepower and performance make it a
blast to drive.
The addition of the Cobalt shock tower brace, Racing Beat sway bars, ILM
front power train and X braces really enhanced the ride - minimal body roll,
comfortable and very responsive.
Your recommendations really helped transform the car from great to
fantastic. Your research, product development and candid recommendations
make you a standout in the industry.
My only questions are - what's next on my list .... And how soon will my
wife want the same upgrades on her 2012 PRHT ...
Again, thank you!!!
